Complete instructions for using our MP3 converter
Converting your audio files is simple and straightforward. Follow these basic steps to get started:
For the best experience, ensure you have a stable internet connection for the initial setup. After the first load, conversions can work offline!
Our converter supports a wide range of audio formats for both input and output. Here's a comprehensive list of what you can work with:
We also support professional and specialized audio formats including AC3, AIF, AIFC, AIFF, AMR, AU, CAF, DSS, M4B, OGA, VOC, and WEBA. These formats are commonly used in professional audio production, broadcasting, and specialized applications.
DRM-protected files (such as iTunes purchases with copy protection) cannot be converted due to legal restrictions. Only convert files that you own or have permission to modify.
Understanding the advanced settings helps you achieve the perfect balance between file size and audio quality for your specific needs.
| Bitrate | Quality Level | Best For | File Size |
|---|---|---|---|
| 128 kbps | Good | Voice recordings, podcasts | Small |
| 192 kbps | High | General music listening | Medium |
| 256 kbps | Very High | High-quality music | Large |
| 320 kbps | Maximum | Archival, professional use | Largest |
Sample rate determines how many times per second the audio is sampled. Higher sample rates can capture more detail but result in larger files:
Choose between mono (single channel) and stereo (two channels):
For most users, 192 kbps MP3 with 44.1 kHz sample rate and stereo channels provides an excellent balance of quality and file size.
Our converter supports batch processing, allowing you to convert multiple files simultaneously with the same settings.
For large batches, consider processing files in smaller groups to avoid memory issues. Keep the browser tab active during conversion for optimal performance.
Our converter works on mobile devices, but there are some considerations for optimal performance:
The converter works on modern mobile browsers including Chrome Mobile, Safari Mobile, and Firefox Mobile. For the best experience, use the latest version of your preferred browser.
If you encounter issues while using the converter, here are common solutions:
Problem: The converter takes a long time to load initially.
Solution: This is normal for first-time use. The converter downloads a 25-30MB library. Subsequent uses will be much faster.
Problem: Browser runs out of memory during conversion.
Solution: Close other browser tabs, try smaller files, or restart your browser to free up memory.
Problem: File conversion fails or produces errors.
Solution: Ensure the input file isn't corrupted or DRM-protected. Try a different output format or quality setting.
Problem: Converted files won't download or are corrupted.
Solution: Check your browser's download settings and ensure you have sufficient storage space. Try downloading files individually instead of using "Download All".
If you experience persistent issues, try switching to a different browser. Chrome and Firefox generally provide the most reliable experience. Ensure your browser is updated to the latest version.
If you continue to experience issues, note your browser version, operating system, file format, and error message. This information helps us provide better support.
